The Galaxy employs a color scheme of dark green with blood-red accents.
Per FM: Warden Clans, page 73.
The Clan Diamond Shark insignia is displayed on all war machines in the Clan Touman. Galaxy insignias may be painted on a 'Mech or fighter, but always lower and smaller than the Clan insignia. Warriors with at least one confirmed kill may paint shark-like teeth in an appropriate place: the nose of a fighter, cockpit of a 'Mech, front of a vehicle or faceplate of battle armor.
The Galaxy insignia is a red coral-like pattern painted around the lower right leg of a 'Mech or armor suit, extending upward in relation to the number of victories a warrior gains.
